The Case of the Counterfeit Eye

It's not hard to see that wealthy businessman Hartley Bassett has killed himself. There's the typewritten suicide note and three guns lying near his body. But for Perry Mason, that's evidence overkill! When Perry Mason meets with Peter Brunold, a man with a missing glass eye, he
doesn't expect to have to play detective to solve the case. But Hartley Basset
is found dead, clutching the missing orb.

Long Synopsis:

When Peter Brunold shows up at Perry Mason's office, claiming one of his glass eyes has been stolen and a counterfeit substituted in its place, who could guess that it would lead to murder? But before you know it, the real authentic glass eye is found. Found in the hand of a dead man. And Brunold has an excellent motive for wanting him dead! He's in love with the dead man's wife.
Was it suicide? Well, a gun is found on the floor of the room. But then a second gun is found under a blanket. Wait! There's a third gun in the dead man's shoulder holster. What's with all the guns? And that typed suicide note is starting to look suspicious. Yup, it's gotta be murder. And Peter Brunold is the one that all the evidence is pointing to.
Can Perry Mason prove his innocence and at the same time point the finger at the guilty party? And can he do it, all the while confounding the new D.A.? You betcha! But why did he just go out and order six custom-made glass eyes?
